HOW TO MOUNT HOLLOWCAGE
Please refer to the video instruction below.  You should mount the cage with the lowest spring tension setting (First hole from left). If you use 11-32T cassette in combination with 52/36T chainrings or bigger you may need to set the cage with middle spring tension setting (middle hole) to account for the chain growth, but only if first position produces loose chain in small - small gear.
